As I understand it, the main languages at Facebook are C++ and PHP, but they use a variety of languages depending on who's doing the work and what part of Facebook they're in. Some of them were using D while Andrei was working there. I don't know if they're using it now or not. But even if some of them are still using D, others could be using Rust or whatever took their fancy and their bosses let them use. IIRC, some of the Facebook guys in London were even using Haskell. - Jonathan M Davis
